SPECIFICATION forming part of Letters Patent No. 395,139, dated December 25, 1888.

` Application filed April 25, 1888. Serial No. 271,815. (No model.)

To all wwnt it 17m/l concern.-

Be it known that I, VILLIAMI II Ess, a citizen of the United States, and a resident of Monroeville, county of Huron, and State oli' Ohio, have invented certain new and useful Improvements in Metal-Seamers, of which the following is a speciiieation, the principle of the in vention being herein explained and the best Inode in which I have contemplated applyingthat principle so as to distinguish it-t'roni other inventions.

My invent-ion relates to scamers for pressing and flattening the seams ot' tin and other reeling material.

It consists of the improvements hereinafter described and claimed.

Referring to the drawings, Figure l is a plan view of the seamer, liig. 2 is a perspective view of the saine. Fig. 3 is a detail view of the wheels and connecting parts. Fig. 4 is a detail view of one of the supports, showing' the ratchet and pawl secured thereon. Fig. 5 is an axial section of the seaming device,

including pressing and guiding rollers, shaft, I

and handles.

A is the bed of the seamer )rovided at its rear end on either side, respectively, with the half-circular supports ai. In the upper portion of each support isthe journal-bearing opening a', in which rests the journal b, with which the roll B is furnished at its respective ends. Secured to one of said journals is the crank C, said journal also having secured to it the ratchet c, engaging with the pawl c, at-

taehed to support d. Hook c? is pivoted to the central portion of the outer face of one of 'the supports a, its upper end hooking over the crank-handle and preventing the displacement of the latter. At the forward portion of the bed and on each side of the saine I secure the upright stanchions D, provided at their upper portion with the cross-bar d. Said stanchions are further provided on their adjacent faces with the vertical grooves CZ.

Guide-beams E extend transversely of the bed A and have secured to their opposite extremities the cross-heads e, that tit into the vertical grooves d and have sliding bearing therein, said guide-beams being some- Followers fare provided, having at their end portions i tenons f', which Alit and have sliding bearing in the said grooves d. On the upper face of each follower a plate, f2, is secured, having bearing against which is the thumb-screw g, that is threaded through each cross-bar d. Intermediate of each follower an d its adjacent cross-head I locate the rubber spring g. On the lower edge of each guide-beam I secure guide-rail 7i, on which the grooved wheels 7i have rolling bearing, said wheels being' joui'- naled on shaft .I on either side of seainerwheel K, that rests in the bed of the seamer and travels on the metallic plate 7n and in. i the space between the guide-beams. At either extremity of said shaft are the handles j, though it is to be understood that I may attach upright handles thereto or handles projecting in any desired direction. Between l the guide-beams andthe roller, and parallel with each, is the compression-roller Z, located close to the bed A and journaled on shaft Z', which is held in position by springs Z2, fastened to said bed. Compression-wheel K and guide-wheels h are j ournaled on shaft J, while the handles lj are rigid with said shaft. The grooved wheels 7i have roller guide-bearing on guide-rails 7l, and serve to guide the compressionroller over the metal to be seained, preventing any tendency to wabble or bind. Guide-bar m extends along one of the longitudinal sides of the bed and has an opening directly under the guide beams, through which the seamer-wheel may pass. At a distance away from the guide-bars about equal to the length of a sheet of tin I secure spring-pressed lug m', working in slot m2 of ordinary construction, by which the tin is held in position while the seamer operates.

The operation is as follows: The sheets of rooiin g material are first properly folded and hooked together, and are then slid onto the bed A between the guide-bar and the springpressed lug, thereby being firmly held in position. The operator then regulates the tension he wishes the wheel to bear on the seam of the tin. Grasping the shaft-handles, the operator then runs the wheel along' the seam, closely pressing and iiattening the same. Thenee the tin is passed under` the roller Z, and thence over the wheel B, on which it is I wound by the turning of the crank. The c011- IOO stant pressure of the spring acting on the roll l keeps the tin in iiattened position and prevents the tin from nnwinding from the reel.

It will be noticed that I provide two handles on the seamer-shaft, and thus the operator may the more easily operate the same and a greater pressure may be brought to hear on the seam, which is a material advantage. Again, the seamer is attached merely to a bed, and not to a table or standard. It may therefore he easily and readily transported from place to place and set upon any convenient bench for operation.

The foregoing description and accompanying drawings set forth in detail mechanism. in embodiment of my invention. Change may therefore be made therein, provid ed the principles of construction respectively recited in the following claims are retained and employed.

I therefore particularly point out and distinctly claim as my invention-- 1. In a seamer, the combination of guideheams provided, respectively, with guide-rails, a presser-wheel, grooved guide-vf'heels on each jacent edges, guide-beams provided with' cross-heads having hearings in said grooves, tension devices engaging' with said guideheams, which latter are provided on their nnder faces with rails, a shaft having grooved bearing-wheels located thereon, and a seamer- Wheel located intermediate of said grooved Wheels, which have bearing on said rails, subsantially as set forth.

In testimony that I claim the foregoing to be my invention I have hereunto set my hand this 16th day of April, A. D. 1888Y J. B. FAY, E. J. CLIMo.
